BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Attached Figure 1 It is a schematic diagram of the internal structure of the spinning assembly of the utility model. DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings.

[0013] As attached Figure 1 The split-flow spinning assembly comprises an outer sleeve 1, in which a fixed block 2, a distribution block 3 and a spinneret 4 are installed from top to bottom. A sand cup 5 is also installed in the outer sleeve 1, and the sand cup 5 is located on the upper outer ring of the spinneret 4. There is a cavity inside the sand cup 5, and the distribution block 3 is installed in the internal cavity of the sand cup 5. A nut 6 is arranged above the fixed block 2, and the nut 6 is threadedly connected to the outer sleeve 1, and the nut 6 fixes the fixed block 2 in the outer sleeve 1.

[0014] A flow guide vertical hole 7 is provided at the center of the fixed block 2, a flow guide gap 8 is formed between the bottom of the fixed block 2 and the top of the distribution block 3, and a flow guide annular gap 9 is formed between the side wall of the distribution block 3 and the inner wall of the sand cup 5. Figure 1 As shown in the figure, the flow guide vertical hole 7, the flow guide gap 8 and the flow guide annular gap 9 are connected in sequence, the upper end of the flow guide annular gap 9 is connected to the flow guide gap 8, and the lower end of the flow guide annular gap 9 extends to the spinneret 4. When the spinning assembly is working, the spinning melt flows through the flow guide vertical hole 7, the flow guide gap 8 and the flow guide annular gap 9 in sequence, and then is ejected from the spinneret hole on the spinneret 4 to form a filament.

[0015] When there are only the diversion vertical hole 7 and the diversion gap 8, the diversion efficiency of the fixed block 2 and the distribution block 3 is low. Therefore, in the present invention, a diversion oblique hole 10 is provided in the fixed block 2, and the upper end of the diversion oblique hole 10 is connected to the diversion vertical hole 7, and the lower end is connected to the diversion gap 8, so that the spinning melt in the diversion vertical hole 7 can enter the diversion gap 8 through the diversion oblique hole 10, thereby improving the diversion efficiency of the fixed block 2. A diversion oblique hole 11 is provided in the distribution block 3, and the upper end of the diversion oblique hole 11 is connected to the diversion gap 8, and the lower end is connected to the diversion annular gap 9, so that the spinning assembly in the diversion gap 8 can enter the diversion annular gap 9 through the diversion oblique hole 11, thereby improving the diversion efficiency of the distribution block 3.

[0016] A diverter protrusion 12 is also provided on the top of the distribution block 3. The diverter protrusion 12 is opposite to the lower end opening of the diverter oblique hole 10, and the diverter protrusion 12 is located in the annular area between the diverter oblique hole 11 and the diverter annular gap 9. The spinning melt flowing out of the lower end opening of the diverter oblique hole 10, under the diverting effect of the diverter protrusion 12, flows partly from the outer edge of the diverter gap 8 to the diverter annular gap 9, and partly flows from the diverter oblique hole 11 to the diverter annular gap 9, so that the spinning melt is more evenly distributed in the spinning assembly, and the quality of the fiber produced by the spinning assembly can be better kept consistent.

[0017] The lower end opening of the diverter oblique hole 10 is in a flared shape, i.e., in a trumpet shape with the opening facing downward. The shape of the diverter protrusion 12 is adapted to the shape of the lower end opening of the diverter oblique hole 10, and the shape of the diverter protrusion 12 is conical. A diverter gap is formed between the diverter protrusion 12 and the lower end opening of the diverter oblique hole 10, and the spinning melt can be diverted from the diverter gap to the outer edge of the guide gap 8 and the guide oblique hole 11.

[0018] The upper opening of the diverting hole 11 is adjacent to the lower opening of the diverting hole 10 , and the upper opening of the diverting hole 11 is also expanded, so that the spinning melt diverted from the lower opening of the diverting hole 10 can enter the diverting hole 11 more easily.

[0019] The number of the diversion holes 11 is the same as that of the diversion holes 10, and the positions of the diversion holes 11 and the diversion holes 10 correspond to each other. There are at least two diversion holes 11 distributed circumferentially at equal angles on the distribution block 3, and there are at least two diversion holes 10 distributed circumferentially at equal angles on the fixed block 2.

[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
